The Estimation Method of Concrete in Structures by Small Size Cores

Abstract

In this study, estimation method for strength of concrete in structures with small size cores whose diameter is from 18 to 26 mm is investigated. The strength of concrete in structures is estimated by this method by using the strength gap between small size cores and standard size cores which are 100 mm diameter and 200 mm height. In the present paper, the results of the basic experiments are described, and the summary of the process of the estimation method with small size cores is explained.
Furthermore, the estimating method to several existing structures is applicated.
